Be it known that we, REUBEN ELLwooD and ANDREW J. UPHAM, both of Sycamore, in the county of De Kalb and State of 1llin0is,have

'- jointly invented new and useful Improvements in Machines for the Manufacture of Barbed Fencing, of which the following is a specification,reference being had to the accompanying drawings,inwl1ich similar letters ofreference indicating like parts-- I ;Figure 1 is. a front view of a machine devised by us, adapted to perform the several requisite operations in the manufacture of barbed wire. Fig.2 is a side view of the same. Fig. 31s a top .view of the lower die and parts connected therewith, and Fig. 4 is a side view of the same. Figs. 5, 6, and Tare side and end views of the upper die-head, and Figs. 8

and 9 are views of parts of the same in section.

Fig. 10 is a view of the feeding device, part of the feed-wheel being broken away. Fig. 11 is axview of the binding-pieces as they appear in a continuous strip. Figs. 12 and 13 are views of a section of fencing, showing one of the positions of the binder during the operationof] manufacture. Fig. 14 is a side view of asection of completed fencing, and Fig. 15

,G D represent feed-wheelshaving suitable hearings on the frame and arranged to feed the E and F are similar wheels located on the opposite side of theframe, and arranged to feed the binders in a continuous strip, and G H are feed-wheels located in the. rear of the frame and adapted to feed the main strip to the dies as it may be required.

The part B has sliding pieces I and J, which are moved to and; from the center of the die by 'wedge-shaped pieces a and springs b. The I motion of the rack m.

die-head K'moves in the part c of the frame, and is moved by theeccentric orcam e, which revolves in the yoke d. The cam e is fixedto the shaft f, which has hearings in the frame,

as shown. This shaftis also provided with eccentrics g and g, which eccentrics give motion to the rods j and 7", whose lower ends are provided with the wedge-shaped pieces a. These pieces operate on like pieces, k, which are attachedto the sliding pieces I and J, so that a downward motion of therodsjjf will force these sliding pieces toward the center of the part B; The feeding device consists of two wheels be- 6 tween which the material to be fed is held. A view of one of the feed-operating devices is shown in Fig. 10, with part of the feed-wheel broken away. The feed-wheel is provided with a ratchet-wheel, 0, which is fixed to and revolves 0 with it. A tooth-wheel, Z, revolves on the same shaft with th e feedwheel, and is providedwith a pawl, n, which engages with theteeth of the ratchet-wheel 0, and thus moves the ratchet and feed wheel in the same direction. The Wheel lis caused to revolve by a downward An upward movement ofthe rack at will revolve the wheel l back to its first position without affecting the position of the feedland ratchet wheels. mittent feed is provided, the time of the opera tion and the length of the throw of which may be varied by varying the position ofthe cams It on the shaft and the position of the collars g on .the rods m. downward by the actiouof the cams h, and are returned to their position by the action of springs 19. By varying the position of the collars on the rods m the return motion of these rods may be varied, and the feed be thus regulated. For instance,if the position ofthe collar on the rod be varied so that the collar will strike against the hearing or. part a and prevent the rod moving upward as far as the cam wouldpermit it to moveQthenthe length of the throwof the rod m will be equal to the extreme distance the collar is moved from the part 00 the length of throw being shortened by moving the collar toward the part'x It will be seen that the distance of I00 revolution of the feed-wheels will be decreased as the distance of the motion of the rods m is decreased, and that the time at which the feed ceases action will always be 'thesanie Thus aninter- So The rack-rods m are forced 8 I t. 6., at the instant the cams h are in the positionshown in the drawings. The feed for the main strand operates in the same manner, excepting that a lever, r, is used to communicate the motion of cam z' to the rack. A spring, 8, returns the rack to its first position, and an adjustable slide, it, regulates thelength of the throw by being moved to and from the piece I, against which it strikes on the return motion.

Theauxiliary feed-wheelsH, F, andD are adjustable to and from their mates by moving the part on which they have bearings toward or from the main or principal feed-wheels. This is done by turning the set-screw shown in Fig. 15. The feeding device may thus be varied to permit material of varying thickness being used. a

The die-head K has the die t, which is held in position by a spring, as shown in Fig. 8, until forced within the die-head or body of the die by the action of the machine.

The part B has a cutting-piece, v, arranged at the proper distance from the center and standing at an angle, as shown, for the purpose of cutting the barb from the wire at the proper time and leaving it pointed. Upon the other side of the part B is the cutter 10, located as shown, for the purpose of cutting the hinders from the strip.

Cutting-edges y and a, which register with the cutting-edges v and w, are attached to the part L, which part slides on the part K during a portion of the operation of attaching the binder 10 to the main strand 12.

The pig x has a cam or wedge shaped head, which,when slightly turned, will draw the pin from the recess in the part K, and thus permit the part L to move upon the part K.

The operation is as follows: The main strand 12, being fed by the feed-wheels H and-G, will move from the rear of the machine toward its front and over the recessed portion of the part B, suitable guides, 1 2, holdingthe samein proper position. The pins 3 4, resting on springs, hold the main strand 12 above the binder l0 and barb 11 until presseddownward by the action of the descending dies. The binder 10 is led toward the center by the feed-wheels E and F, and passes over the cutter to, stopping at a point over the edge of the cutter, as indicated in dotted lines in Fig. 11. The wire ll for the barb is fed by the feed-wheels G and D, and, passing through a proper guide, is fed directly over the cutter 4;. If now, all the materials being in position, as above described, the shaft feontinues to revolve, the cam moving on the yoke 61 will force the die-head K downward, and the die t, first coming in contact with the main strand 12, will bear downward with a slight pressure, sufficient, however, to prevent a disarrangement or movement of the parts when the cutters operate. As the die-head K'continues to move downward, the face of the die t retains its relative position on the strand, and the coil-spring which forces it outward is compressed. The

part L, having the cutters secured to it in po sition, as shown, remains locked to the die-head K until the operation of cutting has been performed, at which point the lever 5 comes in contact with a piece, 6, and the cam-pin x is turned sufficiently to release it from the diehead K; hence the die-head K can continue its downward motion withoutcarrying the part L with it. During the time of the above-described operation the slides I and J retain the position shown in Fig. 2. The upper die, now continuing to move downward, will have compressed the spring 1) until its tension is sufficient to force the main strand, barb, and binder to the bottom of the recess in part B, the binder being bent to the position shown in Figs. 12 and 13, the barb will pass through time of the final pressing, the shoulders of the die it will have bearing against the shoulders of the die-head K, and its face will be flush with the remainder of the die-face t and t form to the shape to which the main strandis to be bent over the barb, thus permitting the sides of the dies to perform the final operation of compressing the binder. A suitable projection, 00 on the part L projects into a groove on the die-head, which terminates at the point the part L is to be fixed to the die-head, thus preventing the part L sliding below the de sired point. The material will ofcourse be fed to the machine in the same relative position as when the fencing is complete-that is to say, the binding-piece will be at the bottom, the barb in the center, and the main strand at the top. It will benoticed that the illustration is out of proportion, the dies and parts directly attached being nearly working size, while the other working parts and frame are very much smaller than will be used in a working-machine. Cams of various shapes may be used to give the desired motion. Binders of various other shapes may be used in a like manner, they being made in a continuous strip.

These may be stamped with a suitable die attached to and operating with the machine, or prepared and fed as herein shown.

Having therefore described .our invention, what we claim, and desire to secure by Letters Patent, is-- 1. In a machinefor the manufacture of barbed fencing, the die-head K, having dies t t t, and
